In computational complexity theory and computability theory, a search problem is a type of computational problem represented by a binary relation. Intuitively, the problem consists in finding a structure y into an object x. An algorithm is said to solve the problem if it behaves in the following way : if at least one corresponding structure exists, then one occurrence of this structure is outputted; otherwise, the algorithm stops with an appropriate output ('Item not found' or any message of the like). For instance, such problems occurs very frequently in graph theory, where searching graphs for structures such as particular matching, cliques, independent set, etc. are subjects of interest.…

In complexity theory and computability theory, an oracle machine is an abstract machine used to study decision problems. It can be visualized as a Turing machine with a black box, called an oracle, which is able to decide certain decision problems in a single operation. The problem can be of any complexity class. Even undecidable problems, like the halting problem, can be used.An oracle machine is a Turing machine connected to an oracle. The oracle, in this context, is thought of as an entity capable of answering some collection of questions, and usually represented as some subset A of the natural numbers. Intuitively then, the oracle machine can perform all of the usual operations of a Turing machine, and can also query the oracle for an answer to a specific question of the form 'is x in A ' There are several different definitions of an oracle machine, all of which are equivalent in the sense that they agree on when a specific function f can be computed by an oracle machine with oracle A.…

In computability theory, Rice''s theorem states that, for any non-trivial property of partial functions, there is no general and effective method to decide whether an algorithm computes a partial function with that property. Here, a property of partial functions is called trivial if it holds for all partial computable functions or for none, and an effective decision method is called general if it decides correctly for every algorithm. The theorem is named after Henry Gordon Rice, and is also known as the Rice-Myhill-Shapiro theorem after Rice, John Myhill, and Norman Shapiro.…

In computabilitytheory and computational complexity theory, a many-one reduction is areduction which converts instances of one decision problem intoinstances of a second decision problem. Reductions are thus used tomeasure the relative computational difficulty of two problems. Many-onereductions are a special case and a stronger form of Turing reductions.With many-one reductions the oracle can be invoked only once at the endand the answer cannot be modified. Many-one reductions were first usedby Emil Post in 1944. Later Norman Shapiro used the same concept in 1956under the name strong reducibility.…

In computabilitytheory, a set is decidable, computable, or recursive if there is analgorithm that terminates after a finite amount of time and correctlydecides whether or not a given object belongs to the set. Decidabilityof a set is of particular interest when the set is viewed as a decisionproblem; a decidable set is also a decidable problem, computableproblem, and recursive problem. The remainder of this article uses theterm decidable, although recursive and computable are equivalent in thiscontext. A language is a set of finite strings over a particularalphabet. A language is decidable (also computable, recursive) if it isa decidable set. A set, language, or decision problem that is notdecidable is undecidable, non-recursive, non-computable, oruncomputable. There are many known undecidable sets; one of theearliest, and most famous, examples is the halting problem.…
